Optical Coherence Tomography (OCT) and ultrasound are both imaging techniques used to visualize internal structures of the body, but they operate based on different principles. OCT uses light waves to capture high-resolution images of tissues, particularly in ophthalmology, while ultrasound employs sound waves to create images of organs and structures within the body, commonly utilized in cardiology. Understanding these differences is crucial in determining their specific applications and advantages in various medical fields.
